Installing cylinder head
  Note
t  There must be no oil or coolant in the cylinder head bolt pockets in the cylinder head.
t  Do not remove new cylinder head gasket from its packing until immediately before installing.
t  Handle new gasket with extreme care. Damage will cause leakage.
t  Renew cylinder head bolts.
–  Place clean cloths in cylinders so that no dirt or emery cloth particles can get in between cylinder wall and piston.
–  Also prevent dirt and emery cloth particles from getting into coolant.
–  Now carefully clean sealing surfaces of cylinder head and cylinder block. When doing this, ensure that surfaces are not scored or scratched (if abrasive paper is used, grade must not be less than 100).
–  Carefully remove metal particles, emery residue and cloths.
–  If crankshaft has been turned in the meantime, position No. 1 cylinder piston to TDC and then turn crankshaft back slightly.
   
–  To centre, screw guide pins -3450/2A- into outer threaded holes on exhaust side.
–  Fit new cylinder head gasket. Inscription (Part No.) must be readable.
  Note
Tensioning roller must be pushed onto studs when fitting cylinder head.
–  Fit cylinder head, screw in 8 remaining cylinder head bolts and tighten by hand.
–  Remove guide pins with removal tool -3450/3- through bolt holes. To do this, turn removal tool anti-clockwise until pins are free.
